Deputies said a worker, Robert Diaz Estrada, admitted bringing the gas to work. He said he was "going to make the other employee think that he was going to throw the gasoline on him in order to scare him," the sheriff's office said.
Estrada told deputies the other employee offended him.
Estrada, 41, was arrested on suspicion of felony menacing for threatening a co-worker and reckless endangerment for putting the other employees and customers at risk of fire.
